Summary

This study aimed to compare the clinical effectiveness of bulk-fill composites with conventionally layered incremental composites in Class I cavities using modified USPHS criteria. Fifty patients were selected based on sample size calculations. Each patient received two restorations, one from each group. Group I received incremental layering composite restorations, while Group II received bulk-fill composite restorations. Group I restorations were placed on the right side, and Group II restorations were placed on the left side. A single trained operator placed all restorations. After one year, the restorations were evaluated using modified USPHS criteria. Periapical radiographs were taken, and postoperative sensitivity was assessed using cold testing (ethyl chloride spray), with pain responses recorded using the Visual Analogue Scale.

Conditions

  • Postoperative Sensitivity
  • Anatomic Form of the Restoration
  • Colour Match of the Restoration
  • Marginal Discolouration
  • Marginal Adaptation
  • Secondary Caries
  • Retention

Interventions

PROCEDURE

Material: Filtek Z250 (3M ESPE, USA)

Group I (Incremental Technique): Material: Filtek Z250 (3M ESPE, USA) Applied in 2 mm incremental layers, light-cured for 40 seconds per increment.

PROCEDURE

Material: Filtek Bulk-Fill Restorative (FBF), 3M ESPE, USA

Group II (Bulk-Fill Technique): Material: Filtek Bulk-Fill Restorative (FBF), 3M ESPE, USA Applied in a single increment (up to 4 mm) and light-cured for 40 seconds.
